TURNING DEVICE FOR CHANNELING AND OTHER LIKE MACHINES.

Specification of Letters Patent Patented June 11,, 1913.

Application filed January 27, 1913. Serial No. 744,348.

To all whom it may concern:

Be it known that I, HENRY H. MERCER, a citizen of the United States, and a resident of Claremont, county of Sullivan, State of New Hampshire, whose post-ofiice address is Glaremont, New Hampshire, have invented an lmproven'ient in Turning Devices for Channeling and other like Machines, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to turning devices for channeling and other like machines. In connection with a channeling machine its object is to provide means for making a quick adjustment of the channeling tool from one side of the track to the other, so that, without the necessity for shifting the trackway itself, there can be cut in the stone a second channel groove parallel to the first.

The trackway for a channeling machine is customarily formed of connected sections composed each of parallel united rails, the sections being laid to form a continuous straight trackway and brought to a level or into alinement by means of blocks placed beneaththe rails.

The labor of shifting such a trackway and adjusting it to a new position forms a very large proportion ofthe labor involved in the channeling operation. This is especially the case with modern high powered channeling machines, where the machines, and consequently thetrackway, are heavy and cumbersome; and is also especially the case in channeling relatively soft stone, where the cut is quickly made while the shifting of the trackway requires the same amount of time and labor.

The object of the present invention is to provide means whereby the channeling tool may be easily and expeditiously reversed in its relation to the trackway, so that after completing a channel groove at one side of the trackway, it may be caused at will to overhang the opposite side of the trackway and cut a second parallel channel groove thereat. The number of times the trackway must be shifted, blocked up, and placed in alinement is thereby reduced onehalf, it being necessary to move the trackway once only for each two outs. This materially reduces the time and expense of the channeling operation.

The invention may be carried out in various ways, but a disclosed in the illustrative embodiment herein described, the reversal of the channeling machine is ob tained by the use of a supplemental track section which is applied to the trackway when it is desired to turn the machine, and on which the channeling machine may be more or less elevated and turned through 180.

The invention will be best understood by reference to the following description when taken in connection with the accompanying illustration of one specific embodiment thereof, while its scope will be more particularly pointed out in the appended claims.

In the drawings:

Figure 1 shows in front elevation a typical form of channeling machine in connection with which my invention may be usefully employed;

Fig. 5 is a longitudinal section in elevation on theline 5 5 in Fig. I;

Fig. 6 is a transverse sectional detail in elevation taken on the line 6-6 in Fig. 1;

Fig. 7 is a plan view of the track section having applied thereto another modified form of turntable;

Fig. 8 i a longitudinal section in elevation taken on the line 8-8 in Fig. 7 and Fig. 9 is a sectional view taken on line 99 of Fig. 7, looking in the direction of the arrow.

The invention may be used in connection with any ordinary form of track channeler, such for example as that shown in patent to Ball No. 555,633 dated March 3, 1896. In

the drawings I have shown a self-propelled I track channeler of the general construction illustrated in my prior co-pending application Ser. No. 475,366, filed February 1, 1909, patented August 3, 1915, No. 1,149,075. As illustrated by the drawings, such chanueler has the truck wheels 14 and supporting main frame or truck support 15. The latter carries the boiler 16, the propelling and toolfeeding engine 17, and tool supporting standard 18, the latter adapted to be adjust ed to either end of the truck upon the trunnion shaft 19, or to be tilted to different inclined positions thereon. The standard can ries a sliding frame including a pressure fluid engine having the cylinder 20 and the attached cross head guides 21, the latter guiding the cross head 22 connected to the tool gang 23 and also attached to the piston rod 24. The sliding frame may, be adjusted toward or from the. work by means of the feed screw 25 connected to the cylinder head and having threaded engagement with a nut in the upper end of the standard, which nut is turned by the beveled gear 26 meshing with the pinion 27. The pinion 27 is mounted upon the shaft 28, the latter being turned by a sprocket chain connection 29 to the tool feeding mechanism upon the truck.

The truck wheels are adapted to move along the rails 30, the opposite rails being connected by tie members such as 31 (see Fig. 4) into sectional lengths, and successive sections being connected to form a continuous length of traclrway for the channeler to travel upon, customarily in a rectilinear path.

In order to reverse the relation of the channeler to the trackway, means are provided for turning the machine relative to the traclrway. This object may be secured in any suitable way, but herein I have shown turning means adapted to be applied to the trackway when desired and on which the channeler may be run. In the form shown in Figs. 1 to 3, inclusive, such turning means comprises a supplemental track section having the rails 35 adapted to be superimposed upon the rails 30 of the usual trackway and having inclined or sloping ends 36 adapted to track with the rails 30, so that the channeler can be easily propelled from the regular trackway 30 to a more or less elevated position on the supplemental rails 35. To turn the channeler when positioned on the rails 35 the latter are connected to form a rigid frame by the transverse angle irons 37, the latter resting upon and fixedly secured to the flange 38 of the removable turning ring 39. The frame, through the flange 38, rests upon a plurality of rollers 40, the lat ter in turn running upon an underlying circular trackway formed by the lower flange of the annular ring 41. The ring 41 has a double angle or approximately Z-shaped cross section. It may be temporarily placed in position on the blocks 42 or, as shown in the drawings, it may be, and preferably is, secured rigidly to the track section having the rails 30 by means of brackets 43 connecting it to the rails and other tie members 44 connecting it to the angle irons 45, which latter are arranged transversely the track section and are connected to the rails 30. The rollers 40 are journaled between two annular bands 46 and 47, the latter forming a roller bearing cage, and, if desired, other rollers 48 may be employed to turn each about a vertical axis and take the side thrust.

During the cutting of the usual channel groove the supplemental traclr section is removed, permitting free travel by the channeler back and forth on the rails 30. When the channel groove has been cut to the required depth and it is desired to start the cutting of the channel groove on the opposite side of the trackway, a supplemental track section is placed in position with the flange 38 of the turning ring resting on the, rollers 40 and with the rails 35 in registration with the rails 30. In this position the channeler is run upon the same as indicated in Fig. 1, whereupon the machine may be turned through 180 and again run off from the supplemental track section and again on to the rails 30. The supplemental track sec tion then being removed, the machine may proceed to cut a channel groove on the opposite side of the trackway.

In Figs. 4 to 6, inclusive, a slightly different form of track section is shown, wherein supplemental rails 50, like the rails 35 in Figs. 1 and 2, are employed and are united into a rigid frame by means of the transverse members 51, but are provided with the flanged rollers 52 which rest upon the fixed circular trackway 53. The latter may be removably held in position, but herein is built into the trackway section having the rails 30, being secured to the transverse members 54 of the track section and at intermediate points to the rails 30.

The rollers 52 are journaled upon stud shafts 55, the latter being fixedly secured, four of them to diagonal brace rods 56, two of them to the transverse frame members 51, and two to the supplemental rails 50.

This form of supplemental turntable is employed in the same manner as the one previously described, the entire frame with the supplemental rails and the rollers 52 being readily removable by lifting the same from the trackway.

In Figs. 7 and 8, I have shown a simpler form of supplemental turning track section. This consists of the supplemental rails 60 united into a rigid framework by the transverse members 61 andthe diagonal members 62. The supplemental track section thus formed provided with a downwardly projecting pivot pin 63 at the point of intersection of the diagonal members 62. The main track section. is also similarly provided with transverse members 64 and diagonal members 65, and at the intersection of the latter there is provided a plate 66 having an opening 67 to receive the pivot pin 63.

The diagonal members 62 on the supplemental track section are substantially flush With the top of the main track section and the diagonal members 65 on the main track section are substantially flush With the bottom of the supplemental track section, so that With the appropriate use of grease or other lubricant the supplemental track section carrying the channeler can be readily turned about upon the main track section, a certain proportion of the Weight being carried by the pin 63.

It will be obvious that While I have herein shown and described my invention as applied to one specific form of channeler, it is applicable to other types of stone cutting machines. Furthermore, While it is here illustrated as embodied in certain concrete and specific forms it is to be understood that extensive deviations may be made from the illustrative forms and from the constructional details shown Without departing from the spirit of the invention.
